Application July 5, 1934, serianV No. 133,910 eclaims. oraal-104) Thisinvention relates to dispensing devices and particularly to means fordispensing coffee, though we do not wish to be limited to this use ofthe structure.

5 The general object of the invention is Yto provide a dispensingdeviceof the character stated which includes a receptacle in which thematter to be dispensed may be placed, a measuring cup or chamber, in oneposition, receiving material from .10 the receptacle, and in anotherposition cutting oil the discharge of material from the receptacle butdischarging material from the measuring chamber, and a detachable cupinto which the material discharged from the measuring chamber l5isreceived. a

A further object is to provide a structure of this character which isvery simple, which may' 2O of contact with the air, and which willsecure a I discharge of a measured quantity of material each time thatthemeasuring cup is shifted` from its l receiving toits dischargeposition.

" Other'objects will appear in the course of the following description.f Y

.j Ourinyentionis illustrated i`n ing drawings, wherein:- Y Figure 1 isaivertical sectional view througha dispensing structure of thecharactersdescribed; Figure 2 is a. fragmentary section in" the sameplane-as Figure 1 and showing the measuring chamber shifted to adischarging position; Figure 3 is a. section through the parts 'shown 'vin Figure 2 but at right angles to Figure 2; 'f Figure 4 is a horizontalsection onthe lineI-l ofliigurel.v Y i... Referring to thesedrawings,'l0 designates a supportingselement preferably of metal whichis contracted toward its lower endas at I I andeprovided with a centralscrew-threaded opening I2. :Atene point on the wall ofthe member I0,there fis provided a bracketll3 whereby this member the accompanyf maybe attached to a wall o r other support. -Disposed' to engage` the lowerscrew-threadedend 4 5 -of,the member I0 is a receiving cup 1l. '111eVscrew-threads engaging the member Il of the member II are ofhigh pitchso that only one-half l turn vof the cup I4 fully engages it with' thesupporting'rnemberll.V A'gasket Ma'isdsposed on I 50 the shoulderfformedexteriorly of thescrewthreads on the neckl of the cup Il.

Disposed above the supporting member is a receptacle I5 which maybe made-of glass, metal or any other suitable material, and it is formed '55,with the inwardly extending flange I6 at its lower end having aVdownwardly extending screwthreaded portion I 1 engaging thescrew-threads formed on the upperend of the member I0. If the receptacleI5 is of metal, then a window I8 must be' provided through which thecontents of 5 the'receptacle can be seen so that the necessityof/refilling the receptacle can be noted. If the receptacle is of glass,of course, this is not necessary. The receptacle at its upper end isprovided with the glass or metal cap I9 which has screwthreadedengagement with the upper end of the receptacle,Y there being a gasket20 disposed upon the shoulder of the cap I9 above the screwthreadedportion.

Disposed upon a shoulder 2l formed upon the upper end of the supportingmember III is a plate 22 of metal, glass or any other suitable materialwhichi'is held in place upon this shoulder by the downwardly extendingannular portion I1 ofthe iiange I6. This plate may.. constitute thebottom 20 of the receptacle I5 but preferably we provide a(YK falsebottom 23 of thin metal or like material which fitted the lower portionof the receptacle so as to form a hopper. This false bottom 23 has acentral opening and the plate 22 has a central opening designated 24.Supported by the plate 22 is a, passageway or guide shown as rectangularin cross section and designated 25. The bottom o f this passageway 251sclosed immediately beneath the opening 24 30 `but; this bottom isprovided with the opening 21 which is entirely out of alinement orregister with the opening 24.v Disposed within this guide or passagewayis a measuring cup 28 which, as i shown, is rectangular in cross sectionand open 35 at the top and bottom. When this measuring c up:

is beneath the opening 24, material from the receptacle l5 will flowinto and filltthe measuringv cup. When the measuring cup is moved so asto register. withthe opening 21, this material inthe -'measuring cup bedischarged into the receivcup M. The measuring cup has attached to itthe plate 29 which, when the measuring V.cup is shifted into alinementwith the openingl 21, acts as a cut-olf for the opening 24 and closesthis opening. De-

pending from the plate .29 is a forked ear 30 and attached to this earinthe :fork thereof is a plung- .er 3I projectingthrough the wall of themember .AII. Springs 32 are attached at their forward' 50 ends to thelateral walls ofthe measuring cup 28 and at their rear ends to ears 33projecting from the wall of the member IIL-these springs 32 acting toretract the measuring cup to the position shown in Figure 1. Obviouslywhen the Y out departing from -the spirit of the invention amount ofunder like situations, the whole unit will be made" larger to hold alarger amount and the measuring cup may be made larger. l

It will be seen that we have provided a canister vfor measuringpredetermined amounts of granular material, such as coiee, tea, ourorthe like, which isl so designed as to be conveniently used 4in thekitchen of a home or of restaurants. It is so constructed as' to beairtight to thus retain the full flavor of the product being dispensed.The several parts may'be readily taken apart-for cleansing or for repairincase any is necessary'.

`While we Nhave illustrated certain details of f construction andcertain arrangementsof parts 'which we believe to be particularlysatisfactory, we do not wish to be limited to these, as obviously manyminor changes might be made therein withas defined in the appendedclaims.
